The Design And Realization Of The Air Mouse

Nowadays,TV's function gets more and more powerful.Many televisions could be able to connect with the network to carry out many emerging businesses,such as Internet on-demand, online shopping,thus traditional remote control couldn't meet the requirements of current technology any more.Now,there is a growing need of practicing the precise locating of the mouse to the traditional remote control.This subject is aimed to make air location to a standard HID device,to facilitate the application later on.In the market of air location,most products are based on the chip of the gyroscope sensor,and some products are using DSP and cameras to capture the location and using algorithm to process the images.The shortcoming of the former is difficult to eliminate the inertia,and the cost of the latter is too high to promotion.Using the special image location processing chip NSM6008,this subject successfully solved the problems of the cost and precise locating.Firstly,this article introduced the programs of the air locating.Then it introduced the related knowledge of USB bus and the realization of the HID devices.Then according to the chosen programs,selected the chip,designed and tested the program.Finally,it made the HID mouse device which can be used in the air.In order to build the hardware system,this article designed the schematic diagram based on the software of Capture and designed the PCB based on the software of Allegro.Both of the softwares are of the company of Cadence.The article realized the transplantation of the firmware program and algorithms based on Keilc 51.The finally experiment showed that the air locating based on the program of NSM6008 could achieve high accuracy and flexibility.
